Abstract: 441,165. Coal-cutting machines. BRITISH JEFFREY-DIAMOND, Ltd., Stennard Works, Wakefield.-(Mitchell, L. E. ; 2666, Summit Street, Columbus, Ohio, U.S.A.) July 30, 1934, No. 1758/35. Divided out of 427,881. [Class 68 (i)] [See also Groups XXIV, XXIX, and XXXIV] In a coal-cutting machine, motor-operated apparatus comprising planetary gearing is provided for propelling the machine, together with motor-operated mechanism for controlling the planetary gear to vary the speed of propulsion. In a machine as described in Specification 427,881, a reversible electric motor P drives the hydraulic pump 444 and also, through gears 331, 332, drives a shaft 373, Fig: 4, splined to the carrier 376 of differential planetary gears 384, 385, which mesh respectively with internal gears carried by a brake drum 387, and a cup member 371 fixed to a shaft 370. A further gear 412, loose on shaft 373, meshes with the gears 384, and is keyed to a brake drum 415. On applying band 391 to the brake drum 387, a slow drive is imparted to the shaft 370, while a fast drive thereto is effected by applying band 391<1> to the brake drum 415. The brake bands 391, 3911 are centrally supported by a bar 395 while the free ends of each band are secured to arms 398, Fig. 8, surrounding the cylinder 400 of a hydraulic motor, the plunger 401 of which is fixed to frame members 404 ; the arms 398 are pressed apart by springs 410 and fluid is admitted through port 408 in the plunger to set the corresponding brake band. The ports 408 of the two plungers 401 are connected respectively to ports 408<1>, 408<11> Fig. 10, of a valve casing 507 with supply connection S and exhaust connections E<1>. The ports 408<1>, 408<11> are controlled by slide valves 510, 512, each with a pin 517, 518, adapted to be engaged one at a time in a slot in a hand lever 508 fixed to an axially movable pin 514; a partition 519 prevents such axial movement except when the lever is in its extreme left hand position, so that the two brake bands cannot be set simultaneously. Restricted ports controlled by set-screws 521, 522 connect the supply S with the exhaust E<1> to limit the pressure of the brake bands. Further ports conduct leakage past packings 523 to the exhaust E<1>. The shaft 370, through gears 334, 335, drives a shaft 336, Figs. 3 and 7, which, through a ratchet clutch 353, sprocket 345 and chain 346 gives a slipping drive to the power cable drum 343, the latter, through chain 348, driving a double screw 349 to move the cable guide 350. An axially slidable rod 359 within the shaft 336 carries alternatively engageable clutch members 360, 438, clutch 360 acting through sprocket 364 and chain 365 to drive the truck supporting the machine and clutch 438 acting through gear 433 to drive a drum 425 for rope haulage of the machine. The truck may be replaced by a sled, endless tracks, &c.

Title: Improvements in or relating to the production of spherical grained smokeless propellent powder
Inventor: O'NEILL JOHN JOSEPH
IPC: C06B21/00
Filed: 1952-01-24
Abstract: 746,661. Making spherical propellent grains. OLIN MATHIESON CHEMICAL CORPORATION. Jan. 24, 1952. No. 1968/52. Class 9(2) Spherical grained smokeless propellent powder having grains 0.025 inches diameter at least is produced by sizing bodies of powder base lacquer, suspending the sized bodies in a medium which is a non-solvent for the lacquer and its components, reducing the viscosity of the lacquer in the sized bodies, maintaining the reduced viscosity until the bodies approach spheri- .cal shape. and then hardening the shaped bodies, all while suspension is maintained. The reduced viscosity may be obtained by the inclusion of solvent in the non-solvent medium, or by heating the medium under pressure. The lacquer consists of a solution of nitrocellulose in a solvent immiscible with the non-solvent medium, and the solution is of such consistency that the bodies are self-sustaining and coherent. The sizing may be by controlled agitation of a curd of lacquer in the non-solvent medium. In the example 3.8:1 ethyl acetate/nitrocellulose lacquer containing stabilizers was disintegrated by moderate agitation in a water bath at 68‹C. While the resulting sized mishapen bodies were in suspension, an emulsion of ethyl acetate and protective colloid in water was added, and agitation continued at reduced speed until the grains are rounded. The additional solvent may be introduced directly into the water bath. Specification 746,705 is referred to.

Abstract: 555,451. Electromagnetic switches; motor control systems. BRITISH THOMSONHOUSTON CO., Ltd. Feb. 18, 1942, No. 2139. Convention date, Feb. 18, 1941. [Classes 38 (iii) and 38 (v)] An electromagnetic switch 13, adapted to cutout the starting winding 62 of a split phase A.C. motor when the speed of the motor approaches the synchronous speed, has an armature 14 pivoted at its centre 32 and held in the " closed " position shown by the attraction of a permanent magnet 50, mounted on the armature, and a fixed "keeper" 51. At its lower end the armature has a pole face 19 which is attracted to the pole face 18 of the electromagnet 13, and the lower end acts with lost motion on a spring 38, carrying the contact 37 which co-operates with a fixed contact 40. The bent centre portion 32 of the armature has side projections which pivot on the frame 12 and passes through a hole in the frame. It is held in place by torques 47 bent out from the spring 36 which is fixed to the upper end of the armature. In operation, increase of motor speed increases the voltage across the starting winding 62 so that eventually the armature 14 is attracted and the contacts 37, 40 opened. A smaller current still passes through the winding 62 by induction from the running winding 61 and this suffices to retain the armature in the attracted position against the bias provided by the permanent magnet 50. Specifications 423,897 and 424,746, [both in Group II], are referred to.
